Abstract: 772,261. Moulding-machines. STONEWALLWORK, Ltd. Sept. 26, 1955 [July 2, 1954], No. 19504/54. Class 83 (1). A shell - moulding machine comprises a vibrator or vibrators which act on the patternplate to eject the pattern from the shell. A pattern-plate 1 is clamped to the underside of an ejector-frame 2 by cams 4 pivoted to posts 3, which stand up from the pattern-plate and pass through holes in the frame 2. Pneumaticvibrators 9, one for each post 3, may be moved to the operative position engaging the posts, the clamps 4 released, and the vibrators set in operation, to cause the pattern-plate to fall away from the shell, which is left supported by the frame 2. The fall of the plate is limited by the cams 4 or other stops. The machine is of the turntable-type, with an oven 16, and the frame 2 is invertibly-mounted on trunnions 19. In a modification, the vibrators are resiliently mounted in rocker-arms on a shaft operated by a pneumatic-cylinder, automatically energized at the correct instant in a cycle of operations.

Title: Process for the manufacture of ketones containing several unsaturated linkages
IPC: C07C45/65
Filed: 1935-07-10
Abstract: Ketones containing several unsaturated linkages are produced by reacting an olefine with a halide of a halogenated carboxylic acid containing at least 3 carbon atoms or of an unsaturated acid and splitting off hydrogen halide from the compound obtained.  The reaction may be effected in the presence of Friedel-Crafts catalysts. In examples: (1) ethylene is passed into a mixture of b -chlorpropionic acid chloride and aluminium chloride and the reaction mixture is poured into aqueous hydrochloric acid and ice; b -dichlorethyl ketone separated and is poured into diethyl aniline at 180 DEG  C. to split off hydrochloric acid and yield divinyl ketone; propylene may be used instead of ethylene with analogous result; (2) propylene is passed into a mixture of aluminium chloride, and crotonic acid chloride with cooling and the reaction mixture is poured into iced aqueous hydrochloric acid; chloropropyl propenyl ketone is extracted with benzene and may be converted to dipropenyl ketone by heating with diethylaniline.

Abstract: 299,904. Oxborrow, P. C. Aug. 3, 1927. Punctures, closing. - Patches for repairing rubber articles, such as the outer covers of pneumatic tyres, are made by assembling two or more plies of cord fabric and the requisite cementing material, with or without an outer layer or layers of rubber, and stretching the assemblage until set sufficiently to retain the threads in stretched condition, vulcanization being preferably effected while the patch is stretched. Plies of cord fabric are cut from stock on the bias, and are assembled with the threads in one ply crossing those in an adjacent ply, together with cementing material and a coating of rubber on one or both sides of the assembly. The patch is then placed in a steamheated mould 14, Fig. 5, which has an interior surface 15 conforming approximately to the shape of the tyre to which the patch is to be applied. A rubber block 18 conforming approximately to the surface 15 of the mould but larger than the patch 13 is then laid on the latter, and pressed down by means of a plate 19, and a screw 24 passing through a pivoted yoke 20. When pressure is applied, the rubber block 18 and the patch expand, and the threads of the fabric are stretched. The rubber in the patch flows outwardly to a feather edge, and the pressure is maintained till the assemblage has set or vulcanized. Fig. 2 shows a completed patch consisting of a ply of skimmed cord fabric 10, three plies of frictioned cord fabric 11, and a layer of rubber 12.
